Answer:
.468
Step-by-step explanation:
The 4 represents your tenths place, the 6 is your hundredths place, and the 8 is your thousandths place.
Plug in 0.9 for x
-(x) + 2.7
- (0.9) + 2.7
simplify
2.7 - 0.9 = 1.8
1.8 is your answer

Answer:
x = 2, y = 7, z = 12
Step-by-step explanation:
x + y - z = -3 (1)
3x - y + z = 11 (2)
x - 4y + z = -14 (3)
add (1) and (2)
4x = 8 x = 2
add (1) and (3)
2x - 3y = -17
2(2) - 3y = -17
-3y = -17 - 4
-3y = -21
y = 7
Find z using any equation
x + y - z = -3
2 + 7 - z = -3
9 - z = -3
z = 12
